After a pretty long build of the llvm11 port, I can at least reproduce =
your error. It looks like the problem is that clang11 does not get any =
--sysroot parameter passed.
If I install the devel/xtoolchain-llvm90 port and use that, I get a =
slightly different command line. Here's both of them, in diff =
--side-by-side format:

So except for the expected difference in the -idirafter option that =
points to the clang internal headers, the main problem is that for some =
reason, clang11 does not get the -target and --sysroot options passed.
